From Niantic:

Get ready to make some waves in Pokémon GO! There’s a global Water Festival in progress, and Magikarp, Squirtle, Totodile, and friends are looking forward to celebrating with you! Starting today at 1 P.M. PDT, you’ll be more likely to encounter Magikarp, Squirtle, Totodile, and their Evolutions all around the world. Additionally, when you’re out exploring areas where Water-type Pokémon more commonly appear, you’ll have a greater chance to encounter several of the Water-type Pokémon originally discovered in the Johto region, and maybe… you might even encounter Lapras.
